    Engineer here.

    This chart seems pretty stupid. I mean, why??? Also, what’s the use of the X-Y graph in inches and millimeters?

    Also, 3/4" converts to 19.1mm, not 19.0mm (19.05 rounds up)

    And anyone who has tried to use metric wrenches as a substitute for the proper size imperial one knows this is only going to work for a couple of sizes. The rest are going to be too tight or usually too loose.

    Are there even any imperial fasteners at all on any new vehicles today???

    This chart be dumb

      Its for workers. You can use 3/4 inch sockets on 19 mm bolts for example, and often the other way around too.

      The graph is there so you have two rulers instead of just having the lines with no use but to show angles and a triangle.

      I’m a HUGE fan of the inclusion of Pythagorean theorem. I can’t tell you how many times I had to check my truck for my crib notes to remember it.
